Activating HTTPS Protocol (Once You Have HTTP)

I have a portal working with HTTP protocol already, but I need to activate also the HTTPS protocol for some specific connections. As far as I know, I should just:

1) Open the https port
2) Include the https ports into the instance profile
3) Change the port mapping of the HTTP Provider Service (ProxyMappings property) on the Java dispatcher. Using the Visual Administrator tool to perform this configuration task.
4) Open the Properties tab of the HTTP Provider Service running on the dispatcher.
Define the port mapping as a value of the ProxyMappings property.
